MAX15006/MAX15007
40V, Ultra-Low Quiescent-Current
Linear Regulators in 6-Pin TDFN/8-Pin SO
General Description
Features
♦ Wide Operating Input Voltage Range (4V to 40V)
♦ Guaranteed 50mA Output Current
The MAX15006/MAX15007 ultra-low quiescent-current
linear regulators are ideal for use in automotive and bat-
tery-operated systems. These devices operate from an
input voltage of 4V to 40V, deliver up to 50mA of output
current, and consume only 10μA of quiescent current at
no load. The internal p-channel pass device keeps the
quiescent current low even at full load. The MAX15007
consumes only 3μA current when in shutdown.
♦ Low Quiescent Current
10µA (No Load) and 90µA (Full Load)
♦ Operates Through Cold-Crank Condition
♦ Withstands 45V Load Dump
♦ Low Dropout Voltage of 300mV
(MAX15006B/MAX15007B)
The MAX15006A/MAX15007A have a fixed 3.3V output
while the MAX15006B/MAX15007B have a fixed 5V out-
put voltage. The MAX15006C/MAX15007C feature an
adjustable output from 1.8V to 10V. The MAX15007
includes an enable input to turn the device on or off. All
devices are short-circuit protected and include thermal
shutdown.
♦ Stable Operation with Tiny 2.2µF Output Capacitor
♦ Enable Input (MAX15007)
♦ Preset 3.3V and 5.0V Output Voltages
♦ 1.8V to 10V Adjustable Output (MAX15006C/
MAX15007C)
♦ Thermal and Short-Circuit Protection
The MAX15006/MAX15007 operate over the -40°C to
+125°C automotive temperature range. These devices
are available in space-saving 3mm x 3mm 6-pin TDFN
and 8-pin SO thermally enhanced packages.
♦ -40°C to +125°C Operating Temperature Range
♦ Thermally Enhanced 3mm x 3mm 6-Pin TDFN/

board. For detailed information on package thermal considerations, refer to www.maximintegrated.com/thermal-tutorial.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

MAX15006/MAX15007
40V, Ultra-Low Quiescent-Current
Linear Regulators in 6-Pin TDFN/8-Pin SO
EN Input (MAX15007 Only)
Detailed Description
EN is an active-high, logic-level enable input that turns
The MAX15006/MAX15007 high-voltage linear regulators
the device on or off. Drive EN high to turn the device
on. An internal 0.5μA pulldown current keeps the
MAX15007 in shutdown mode when driven by a three-
state driver in high-impedance mode, or an open-drain
driver. While in shutdown, the device consumes only
3μA (typ). EN withstands voltages up to 40V, allowing it
to be driven by high input level voltages or connected
to IN for always-on operation.
operate over a 4V to 40V input voltage range. These
devices guarantee 50mA load drive, and offer preset
output voltages of +3.3V (MAX15006A/MAX15007A) or
+5V (MAX15006B/MAX15007B) or an adjustable voltage
output from 1.8V to 10V (MAX15006C/MAX15007C).
Thermal shutdown and short-circuit protection prevent
damage during overtemperature and overcurrent condi-
tions. The MAX15007 includes an enable input (EN)
allowing the regulators to be turned on/off using a logic-
level voltage. Driving EN high turns on the device while
driving EN low places the device in a low-power shut-
down mode. In shutdown, the supply current is reduced
to 3μA (typ). The MAX15006/MAX15007 operate over the
-40°C to +125°C automotive temperature range. All
devices are available in thermally enhanced 6-pin TDFN
and 8-pin SO packages capable of dissipating 1.904W
Thermal Protection
When the junction temperature exceeds +165°C, an
internal thermal sensor turns the pass transistor off, and
allows the device to cool. The thermal sensor turns the
pass transistor on again after the junction temperature
cools by 20°C. This results in a cycled output during
continuous thermal-overload conditions. Thermal pro-
tection protects the MAX15006/MAX15007 in the event
and 1.860W at T = +70°C, respectively.
A
of fault conditions. Operation at T = +150°C without
J
going into thermal shutdown is not guaranteed. Use
Figures 3a and 3b to determine the minimum guaran-
teed output current.
Regulator
The regulator accepts an input voltage from 4V to 40V.
The MAX15006A/MAX15007A have a fixed 3.3V output
voltage while the MAX15006B/MAX15007B offer a fixed
5V output voltage. The MAX15006C/MAX15007C fea-
ture an adjustable voltage output by connecting an
external resistive divider from OUT to FB and to GND
(see the Output Voltage Setting section).
Output Short-Circuit Current Limit
The MAX15006/MAX15007 feature a 175mA current
limit. The output can be shorted to GND for an indefinite
period of time without damage to the device. During a
short circuit, the power dissipated across the pass tran-
sistor can quickly heat the device. When the die tem-
perature reaches +165°C, the MAX15006/
MAX15007 shut down and automatically restart after
the die temperature cools by 20°C.

Available Output Current Calculation
The MAX15006/MAX15007 provide up to 50mA of contin-
uous output current. The input voltage range extends to
40V. Package power dissipation limits the amount of out-
put current available for a given input/output voltage and
ambient temperature. Figure 5 shows the maximum
allowable power dissipation for these devices to keep the
junction temperature below +150°C. Figure 5 assumes

For stable operation over the full temperature range
and with load currents up to 50mA, use a low-ESR
2.2μF (min) ceramic or tantalum output capacitor. Use
larger output-capacitor values such as 22μF to reduce
noise, improve load-transient response, and power-
supply rejection.

Some ceramic dielectrics exhibit large capacitance and
ESR variations with temperature. Ensure the minimum
capacitance under worst-case conditions does not
drop below 1.3μF to ensure output stability. With an
X7R dielectric, 2.2μF should be sufficient at all operat-
